and third legs greatly enlarged, the end segments turned diagonally 

 inward, each with four huge divergent spines. Endopods of both 

 these legs 2-segmented, end segment of second endojood with a long 

 inner spine, enlarged and sharply curved at its tip. End segment of 

 third endopod much dilated distally, with two apical and two inner 

 setae, and a stout blunt spine outside of the apical setae with tubercles 

 at its base. Fifth legs reduced to a narrow lamina, with a distinct 

 outer process, but no division of basal expansion and distal segment, 

 the lamina armed with three filiform setae; the genital segment car- 

 ries the rudiments of a sixth pair of legs. Total length, 0.7-0.8 mm. 

 Remarhs. — Sars's statement that this is a littoral species found 

 among algae and sometimes in tide pools is abundantly confirmed in 

 the localities from Avhere the present specimens were obtained. The 

 female can be distinguished by the details of the first and fifth legs, 

 the male most quickly by the long spine on the second endopod. 



This is its first appearance in American 

 waters.

 FeTTiale. — Body conspicuously depressed, the segments separated by 

 rather deep constrictions; cephalic segment shorter than the rest of 

 the metasome; rostrum short and broad with prominent apical fila- 

 ments; second and third segments very nearly as wide as the head, 

 and longer than the narrowed fourth and fifth segments. Urosome 

 little more than half the length of the metasome, its segments well 

 produced laterally; caudal rami as long as anal segment, apical 

 setae three-fifths the body length. First antennae 7-segmented, the 

 two basal segments enlarged, the second segment with several dorsal 

 setae, the third segment narrow and elongate. First legs slender, the 

 endopod twice the length of the exopod, its basal segment with a few 

 long inner hairs ; end segment of first exopod with two apical genicu- 

 late setae and two outer spines. Distal segment of fifth legs reaching 

 three-fourths of its length beyond the basal expansion, densely cov-
